Code.appinventor.mit.edu doesn't work well

The site: code.appinventor.mit.edu
doesn't work well, and it exits me when I do any action

Hello Entesar Batiha

Welcome to the Forum. You seem to have hit an unusual problem. I just ran a test, everything is good on 'http://code.appinventor.mit.edu'

  1. Can you be more specific about the 'action' that causes the 'exit'?
  2. Can you use the regular Server, 'http://ai2.appinventor.mit.edu' ?

Does this happen before, or after, you connect to the Companion?
